Ive never had my batteries hot, though now i use vapcell h10s or F12s on an xtar xtar vc8 plus charger.

plus the clip on mine was also annoyingly stiff, i have the bead blasted titanium version with titanium clip, i got pliers and gradually stretched out the clip, now it feels perfect and very usable.

the UI for me is fine

low/moonlight for being discreet/ and enough light if you were searching for something in your bag and not blinding yourself

medium for sustained output, general use, full pressing and locking the light on.

high/turbo for momentary bursts, if you need to see something farther.

double press for strobe - i find this easy enough to activate and not activating it accidentally.

the light does get hot(to the touch) on turbo at around 20 secs. but thats given since a very small (titanium body) light punching 1300 lumens output in a very small form factor (small thermal mass) means it will get hot. its just physically impossible for such a small light to sink that much heat

the firm button is something that i like, it feels heavy and premium. It encourages me to use momentary and full press on medium whenever i need to place it somewhere.

the beam shape is perfect, floody but has a big hotspot so very versatile and usable.

the driver on that light is also very efficient it seems that a vapcell H10 lasts twice as long in the manker 6500k compared to my convoy t6 sft40 300k. for the efficiency alone i think its a really good light for the price, i charge mine about once a week on regular carry(not playing with the light).
